We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment

2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer 810B away from moisture, excessive sunlight and dust

2. Connect the composite video BNC OUT 2 connector to the composite
acceptor (for example, a genlockable camera).
3. Connect the s-Video (Y/C) 4-pin Y/C OUT connector to the s-Video (Y/C)
acceptor (for example, an AV diagnostic switcher).
4. Connect the 3-wire cable to the detachable terminal block 1kHz OUT
connector and to the audio input of the destination unit (for example, the AV
diagnostic switcher).
5. Connect the 12V DC power adapter to the power socket and connect the
